- 🌍 The ocean is one of nature's most beautiful gems. It is home to an incredibly beautiful and rich flora and fauna.
Since the beginning of human history, men have been closely linked to the sea and passionate about this blue immensity. The underwater depths are all the more coveted and fascinating as they still remain a mystery despite all the technical inventions we are capable of.
Man can travel on land, on sea, in the air and even in the universe. He has walked on the moon, observed and studied many planets thanks to state-of-the-art tools. Man's knowledge of the environment that surrounds him has become more and more extensive over the centuries.
For all that, there is still one great unknown in this equation of human knowledge: the ocean in its vastness.
🔥 As a reminder, videos are published on SUNDAYS at 6:00 PM.

💥 Oceanic Deep Voyage:
- In these ocean depths, hydrothermal springs (hot water source due to cracks near the magma) allow bacteria to proliferate. These bacteria transform chemical compounds into sugars that other marine species can feed on. Millions of animals depend entirely on the work of these bacteria. They are the only ones able to produce organic matter.
Our knowledge is still very limited on the subject, but we already count more than 600 species living near these sources. The further away from these springs, the more deserted the regions are. The oceanic geysers are the only nutritive sources for many animals.
The order is perfectly established around the hydrothermal vents. At the closest point to the vents, the temperature is between 40 and 100 °C. As you can imagine, not all species can survive under such heat. Some worms are perfectly equipped for this. This is the case of the Pompeii worm. Man named it after the ashes that fall on it all the time. This worm is quite different from the tube worm that we met in the abyssal zone. This one has a digestive system, a mouth, an anus and even a nervous system and a brain.
A little further, where the water oscillates between 10 and 35 °C, we find again worms which live in colony like the tube worm. Around this area, many marine animals use symbiosis to survive. Bacteria use the sulfides in the water to produce energy and sugar. They create micro-organisms that allow other species of mollusks, crabs, mussels or shrimps to survive. We also meet other fish, such as the hydrothermal lycode which feeds on these marine species. It is one of the few fishes to adapt to such living conditions. Its body is white and without scales. It always swims close to the bottom, slowly.
Other species have managed to find techniques to feed themselves, but also to save a maximum of energy. Life at this depth requires an extreme adaptation. Some shrimps for example are blind and do not use their digestive tract. They fix all the energy at the level of the head in order not to draw too much from their vital resources. They consume the bacteria of their own organism.
The yeti crab, on the other hand, uses the silk of its claws to collect the bacteria it feeds on. The symbiont is therefore outside its host.

Hi there. I'm struggling a bit with a statement you make 1 minute 34 seconds into the video. You state the deepest abyss is 11000 meters (=11 kilometers) - or 36000 miles? In fact 11 km equals some 7 miles, you seem to have misconverted those ;-)
Yeah when I heard that any credibility disappeared not even gonna watch any farther
@@craigbinder5560 A shame because the rest of the video is accurate with great cinematography.
He meant feet
Yeah that got me also. I'm sure he just got his numbers mixed up because that would be deeper than the Earth is round. Still enjoyable video
He mistakenly said over 36k miles which should have been over 36K feet.
Just FYI, the fault mentioned is not a transparent fault but instead are called transform faults. Otherwise, a great video, with lots of information.
Also, the deepest spot in the ocean is the Challenger Deep which is about 7 miles down. However, the collectvie length of the midocean ridges is about 36,000 to 40,000 miles.
That was an enjoyable voyage.
Great work. Thank u!
So amazing
Really good doc. Keep them coming.
How in the heck are mermaids Machiavellian? ? That is a very strange statement.
Cool video! I’ll pass on the 36,000 mile thing we know the deepest point of the trench is 7 miles. Keep the vids coming, I love the space ones!!
Could he be referring to the collective length of the midocean ridges that wind around the globe, which total 36,000 to 40,000 miles/
He just meant feet.
‘sp?!yeah!you made amazing ~ catch you later!friend-
"We know that the deepest abys is 11,000 meters - that is more than 36,000 miles - it's incredible to think that the ocean can be that deep isn't it?"... WTF? If it were that deep we'd dive into one ocean, travel straight through the centre of the earth and pop out of the opposite one and then head straight off into space. He meant feet but I couldn't resist taking the piss out of the glaring opening mistake.
He meant feet, it was a simple mistake. Go read an old medical journal or space related text book.
My dudes. He meant feet when he said miles. Slip of the tongue. An error - yah but how is it nobody realized that’s the simple error he made in any of the sometimes snarky comments?
People know, but they like to make themselves feel special by pointing out other's errors.
True but if you want to look smart be smart. Check your video before posting. Write 1st then edit.
Dang i never knew the deepest part of the ocean is 36,000 miles.
I believe he meant feet lol. 7 miles is the deepest part
Ya 36,000 feet approx 11,000 meters or 6.8 miles
50 meters is almost 50 feet? Check you math sheesh!
The number itself is quite interesting, don't they suspect that at least one of the icy moons in our solar system has a depth even exceeding that under the ice layer? One has to wonder is there anything under that ice or is it just water and no life at all.
Right? You dive in, keep swimming straight ahead and you'll pop out at the other side of the planet
STOP! You are not the first person to notice a simple mistake made in the first 2 minutes of the video. Comment something else!
36,000 miles? Bit of a slip there. Otherwise, superb video. But work on the editing.
I think the 36000 miles deep thing Is off some what.
Only a little off though :-D
Imagine posting the same comment mentioning the miles instead of feet mistake over and over again instead of posting something worthwhile. Yes, a mistake was made, and you weren’t the first one to notice. Go read an old medical journal or old space text book and you will see that plenty of much more authoritative academics have also made mistakes while trying to convey factual information. He probably just reading something someone else wrote anyway.
That's a very erroneous statement at the beginning. 11,000 meters is 6.835 miles.
This video is riddled with errors, not recommended
the oceans only 11 miles deep
I don’t usually care but the overuse of “man” to mean people or humans got distracting and took me out of the moment. I’m a little disappointed
You need to do a better study the deepest part of the ocean is 36,000 ft not miles
Even if 36,000 miles is an error in conversion, wouldn't the person doing the narration have realized the obvious mistake? Wasn't this video reviewed for errors before it was posted? Obviously no to both of those. So thumbs down for the completely amateurish mistake.
Fluctuating volume, terrible background music, unwatchable
36,000 miles deep huh ? Lol...lol... I don't know about that !!! Lol..lol...
